●4 to 6 sets of 0-9 cards

Deal cards so that each has an equal number in their decks. All players turn their top card face up and whoever can call out the correct sum of the total of all turned up cards first wins all the cards. If a player calls out the wrong sum, he must remain quiet while another player tries to give the right answer. The winner of each play puts his cards on the bottom of the deck. Game continues until time is called, or one player has all the cards. This one can get pretty competitive, so watch out!

Variation: Subtraction Showdown. Using two players, deal half the deck to each person. Both turn their cards over at the same time. First player to subtract one from the other and call out the correct difference, wins both cards.
